    Abstract: PROBLEM TO BE SOLVED: To provide a method and a system which cause certain microparticles to concentrate and disperse in a microfluid.SOLUTION: The microfluid system includes a piezoelectric base material 1, a wave-generating means 3 which generates waves in the piezoelectric base material, and an operating surface 2 which distributes the generated waves. A fluid droplet 9 is disposed on the operating surface. By changing power applied to the wave-generating means or distribution of waves traversing the operating surface, particles floating in the fluid droplet is caused to disperse in the fluid droplet, to concentrate in a certain area in the fluid droplet, or to rotate in the fluid droplet.

    Abstract: A system (100) for transmitting digital information includes a transmitting apparatus (102) for generating an optical signal bearing digital information, a dispersive optical channel (104), and a receiving apparatus (110) for receiving the optical signal. The dispersive optical channel (104) is disposed to convey the optical signal from the transmitting apparatus (102) to the receiving apparatus (110). The transmitting apparatus includes an encoder (114) for encoding digital information into a series of blocks, each including a plurality of data symbols corresponding with one or more bits of digital information. A signal generator (118) generates a time-varying signal corresponding with each of said blocks. An optical transmitter (136) is arranged to apply the time-varying signal to an optical source (138) to produce an optical signal which includes an optical carrier and substantially only a single information bearing optical sideband in an optical frequency domain, the sideband corresponding with the time-varying signal. The receiving apparatus (110) includes an optical detector (146) for detecting the optical signal to produce a corresponding received time-varying electrical signal. The receiver further includes means (166) for generating a series of received data blocks from the time-varying electrical signal. An equalizer (168) performs an equalization of received data symbols included in each data block to mitigate the effect of dispersion of the optical channel, thereby enabling the transmitted data symbols to be recovered.

    Abstract: A method for the preparation of a stable, liquid formulation of growth hormone, comprising growth hormone, a buffer and a stabilizing effective amount of at least one stabilizing agent selected from the group consisting of: (i) polyethylene-polypropylene glycol non-ionic surfactants, (ii) taurocholic acid or salts or derivatives thereof, and (iii) methyl cellulose derivatives, wherein the method comprises admixing the growth hormone with the buffer and the stabilizing agent(s) under conditions such that the growth hormone is not exposed to concentrations of the buffer or stabilizing agent(s) which are greater than 2x the final concentrations of the buffer or stabilizing agent(s) in the formulation.
